America's Most Dangerous Construction Project — And History Forgot Their Names

They were told it was impossible: no railroad could ever climb the wall of mountains between the two coasts of a continent, rising seven thousand feet in a hundred miles, through granite so hard that explosives barely scratched it. Yet over six brutal years, tens of thousands of workers cut a path straight through — blasting tunnels by hand, lowered over cliffs on ropes, buried under forty feet of winter snow. When it was done, a journey of over a month collapsed into less than a week. And the men who did the hardest, deadliest work were left out of the photograph that celebrated their own victory. This week on Iron & Legend: how the Transcontinental Railroad conquered the Sierra Nevada, the astonishing and terrible work done by the Chinese laborers who made up most of the workforce, and the uncomfortable question of who a triumph like this truly belongs to. Does the achievement belong to the names in the history books — or the forgotten hands that actually built it? Tell us where you land in the comments. We read them. Built by people who believed it could be done. And that's worth remembering. Subscribe and turn on notifications — every week, one machine.
